Haha! Yes, that picture you gave was from Ohayocon this year. I saw that guy there, and he's my HERO. I'd NEVER have the guts to wear Kuja's outfit in public.
And I'm still amused that the Kuja cosplayer there is male and the Zidane is female. Not what one would normally expect, hmm?
Of course, I'm STILL waiting to see a full plate-mail Steiner costume, complete with clanking sounds.
